DOCUMENTATION 

NOTE:  The purpose of this technical documentation section is to provide a guide to the TWTA for technician-

level servicing. It is intended for use by qualified technical personnel who must troubleshoot and 
repair the TWTA in the field. Such repairs are typically limited to replacement of modules or major 
components. For this reason, only documentation pertaining to the highest levels of the system and to 
system control logic is included.
